Just wondering,

Is the only way to achieve Fault Tolerance for the ZCM database installing it on two clustered servers? Also, is it fully supported in a clustered environment?

If I were to lose the Primary Server hosting the database in a non clustered setup, could I restore it to a second Primary server in the Zone or would I have to reinstall the first Primary server then restore the database?

What fault tolerance is built into ZCM by default if any? If my database is down, what happens to all of my users if I lose the Primary Server hosting the database?

Thanks for answering all of my questions.
